I sended my paper proposal and waited for a replay, some week after I got a
invite to partecipate at the Kernel Keynote.
I thought partecipating at the Kernel Keynote as mentor and doing a presentation
was a good way to talk about Gentoo Kernel Project and how to contribute in the
Linux Kernel and Gentoo Kernel Project.
Also my paper got accepted so I could join OSS Japan 2017 as speaker.
It was three really nice days.

Presentation:

Fast Releasing and Testing of Gentoo Kernel Packages and Future Plans of the Gentoo Kernel Project

One interesting part was about how to contribute to the Linux Kernel.
After some information about Linux Kernel contribution numbers the talk moved on
ho to contribute in the Linux Kernel.
For contribute in the Linux Kernel there is need of some understanding of C
and running test in the Linux Kernel.
Like fuego, kselftest, coccinelle, and many others.
And also a good talk from Steven Rostedt about working with Real-Time patch.
